I was running a stock toyota recirc blow off valve at 25psi boost and let me tell you the stock valve wasn't meant to handle that kind of boost. At 7000 RPM in 3rd one day my cylinder head all of a sudden lifted and started pouring oil out of the cylinders and turbo. It turned out that at 25psi boost the diaphram tore and the spring and pintle met up with the compressor wheel of my T3/T4 and ripped it apart and apparently that much oil will cause one hell of a lean condition. I'm now running a GT3082R with an .84 exhaust AR and a 38mm turbosmart recirc blow off valve and I've had no problems or complaints with it and is extremly easy to adjust.
